Hand-painted ceramic wall plaque, blue and gold

I lost my hand-painted ceramic wall plaque yesterday around 3pm. It’s an Art & Decorative Items piece, about 8 by 10 inches, glazed cobalt blue with gold flecks, and it’s signed with the initials 'ML' on the back. There’s a tiny chip on the lower-right corner and a faint crack along the left edge. I was outside the Yale University Art Gallery on Chapel Street in New Haven when I last had it. It was a gift from a local artist friend and means a lot to me—sentimental value, really hoping to get it back. If anyone found it, I’d really appreciate getting it back near the Yale campus or at my place in New Haven.
